2 or More
Two players play off against one another in a head to head battle. People can pick teams and back the guitar hero players to make it more interesting. (This means they drink when the players have to)
Flip a coin and the winner gets to decide the song that is played. For every 3 colours missed the player must take a drink (The colours missed while drinking don’t count). For every power streak that a player gets, the opposite player has to take a drink.
Once the game is over the loser has to take a shot and the winner decides what the shot is.
